The engine can not start / not start seven common reasons

Under normal circumstances all the engine , the starter or the battery is faulty will be difficult

to start the engine , can not even start. In this case, we must first understand the starter and

battery usage, in order to roughly determine the fault location. If the battery usage time has been

more than one year should focus on checking the technical condition ; If the battery usage time is

shorter, but not overhaul the starter for a long time , you should check up from the starter .

Then analyzed and processed according Symptom startup :

1 , only to hear the starter solenoid switch "giggle " sound at startup , or when you first start

the starter drive slowly turn the crank a few times , followed by start solenoid switch "giggle "

sound , but do not turn the crankshaft . This phenomenon is generally belong battery "off grid"

failure.

2 , temporary parking starts every time , but the next day to start or stop a long time but it can

only make crank it. This phenomenon is part of a battery self-discharge is serious, its plates,

separators serious aging , indicating that the battery is close to retirement .

3 , when you start turning suddenly unable to start the machine , accompanied by burning rubber

smell or smoke coming out of the battery , mostly pole piles, poles pile burning fever clip poor

contact .

4 , if the starter drive gear and start the engine flywheel ring gear issued by the impact of idling

sound, for two reasons : First, engage the flywheel ring gear cut surface deformation ; Second,

starter drive gear and flywheel ring gap is too big . Both can not engage the engine will not start.

5 , a power switch is turned on , the starter drive gear on the flywheel ring gear and rotate

together . This failure , one starter solenoid switch holding coil connected to the wrong power

supply terminal ; Second, the three key switch on the line wrong, judgment is: the key in the " 0 "

position starter drive gear does not turn, the starter motor drive gear in the " 2" position is

rotated together with the flywheel ring gear.

6, the start switch is turned to the start position of the engine can not be started , and no other

phenomena . This failure , one key switch is turned on due to wear without starting circuit ;

Second, the starter relay is not turned starter solenoid switch circuit ; Third, the power switch is

not turned on the main circuit .

7 , only a slight "click " is heard , no any response, which is due to start issuing start relay .

Then just click on the electromagnet tail , forcing the solenoid forward, to the start-up circuit is

turned on , so that the engine starts.
